Abstract: Un circuit de minuterie a intervalle comprenant un comparateur unique (12) ayant une premiere (14) et une seconde (16) entree et une sortie (18). Le circuit comprend des moyens de resistance et de capacitance (R1, R2, C1) relies en serie possedant un point de controle (A) lequel est relie afin de faire varier la tension de la seconde entree (16) du comparateur. Une premiere tension de reference est etablie par un premier moyen (R3, R4) a la premiere entree (14) du comparateur de facon telle que sa sortie (18) change depuis un second etat vers un premier etat lorsqu'une tension en augmentation au point de controle (A) excede la premiere tension de reference. Un second moyen (R4, R5, CR2) etablit une seconde tension de reference a la premiere entree (14) du comparateur en reponse au premier etat a la sortie de celui-ci. Un troisieme moyen de diode (CR1) produit une tension decroissante au point de controle (A) en reponse au premier etat et lorsque la tension decroissante au point de controle (A) est plus petite que la seconde tension de reference, la sortie (18) du comparateur change vers son second etat pour repeter le processus.

Abstract: A bearing assembly suitable for use as a trolley wheel for overhead conveyors, includes a multipart inner race (36, 50) in which one annular part, preferably machined from steel, bears the major loading on the assembly and the other annular part, preferably formed from sheet metal, bears only minor loading. The major load bearing inner race part (36) extends on either side of the minimum diameter of the inner raceway and allows a full complement of balls (30) to be inserted in place between the inner and outer raceways without heating and expansion, or contraction, or any other treatment of the inner or outer race parts. The minor load bearing inner race part (50) is preferably clamped to the major load bearing part (36) and provides a contoured extension of the major load bearing raceway for guidance and ball retention purposes. Preferably, the outer race outer circumference is curved to accommodate a sloped support track in overhead conveyors such that the loading force is directed through the balls (30) to the major load bearing inner race part (36).

Abstract: When machining waveguides a problem exists because of the flexing of the machining tool, this leading to inaccuracies in the waveguide. This is especially pronounced for narrow waveguides designed for high frequency operation since the tool has had to be of correspondingly narrow diameter, In Figure 2 a number of waveguides having a narrow dimension W are formed by interdigitated projections (6, 6A) on two piece of material 1 and 2. These intedigitated projections are produced by machining relatively wide parallel grooves in the two pieces of material and this can be done using a relatively large diameter tool which is not appreciably subject to flexing during operation. The result is relatively accurate, narrow waveguides of high surface finish unobtainable using conventional techniques.

Abstract: A screw fastening between a lath (2) and a ceiling or wall (1) of a construction, wherein a retaining screw (9) extends from the under or outer side of the lath through a screw-receiving bore (4) into a plug (3) set in the ceiling or wall, and is screwed to the latter. In order to compensate for unevennesses of the ceiling or wall, the head (8) of the retaining screw (9) is clamped into the lath in such a way that it is mounted therein without axial play, but able to rotate. This is effected by a supporting disc (6) which has a central screwdriver passage (7) of smaller diameter than the retaining-screw head (8) and is screwed to the underlying structure (lath 2) by means of a plurality of supporting screws (11, 12) distributed over the periphery. The head of the retaining screw (8) thus lies, in its side facing away from the ceiling or wall (1), against the supporting disc (6) and, on its side facing the ceiling or wall (1), either against the lath (2) or - according to a further development of the invention, against a counter supporting disc (10) which, for its part, is screwed to the lath (2) by means of fastening screws (11, 12). <IMAGE>

Abstract: In order to allow an adjusting of the bending tools to a given diameter of the wire being bent allowing the producing of the requisite bending radius a central mandrel which forms two bending or forming, respectively, jaws is replaceable together with a shearing tool. To this end a hollow shaft is mounted at the rear of the central mandrel, which shaft is mounted to a supporting shaft by means of a screw joint. The supporting shaft is supported in turn rotationally and can be rotated by means of a motor in order to disconnect the central mandrel. By mentioned rotation the screw joint is released. A special coupling of the shearing tool to an axially movable operating shaft allows a simultaneous disconnecting of the shearing tool together with the central mandrel. A bending mandrel is mountable at locations having various radial distances from the central mandrel. A cover plate provided with a position control element operates together with proximity switches such that two defined initial angular positions of the bending mandrel is maintained independently from mentioned adjustments.

Abstract: The present specification describes a seat (5, 7) for use in an automotive vehicle (3). Conventional automotive vehicles (3) provide difficulties when required for use by handicapped persons. Such difficulties are especially highlighted when a handicapped person who uses a wheelchair (25), requires the wheelchair (25) to also be transported in the automotive vehicle (3). Conventional two door vehicles (3) provide a severely restricted amount of space (17) between the back sections (7) of the front seats (5, 7) and the sides (29) of the vehicle body, preventing the storage of wheelchairs (25) in the rear (27) of the vehicle (3) and providing only restricted access to the rear (27) of the vehicle (3). 
     The present specification describes an automotive vehicle seat (5, 7) for use in an automotive vehicle (3), which seat (5, 7) is especially useful in adapting a standard motor vehicle (3) for use by a handicapped person, the seat (3) enabling a wheelchair (25) to be simply stored in the rear part (27) of the vehicle, and allowing access to the rear of the vehicle to be increased. The seat comprises a back section (7) and a squab (5), the squab (5) being adapted to be pivoted about a generally vertical axis and the back section (7) being movable relative to the squab (5) in a generally horizontal, lateral direction, as and when required. When the squab (5) is pivoted and the back section (7) moved laterally, access to the rear (27) of the vehicle (3) is thus considerably increased, allowing, for example, a wheelchair (25) to be easily moved into and stored in the rear (27) of the vehicle (3).
